A shorter lead or a slip collar won't solve pulling. At best, they suppress it for the moment. What really helps is training, and that starts with understanding why your dog pulls in the first place.
Why dogs pull
Most dogs pull because it works: they get to where they want to go faster. So pulling gets rewarded over time, without you ever intending it.
The stop method
Stand still as soon as the lead goes tight. Only walk on again when it hangs loose. At first, a short walk takes much longer this way, but your dog learns: pulling doesn't get him a single metre further, a loose lead does.
Changing direction
If your dog pulls in one direction, turn around and walk the other way. No command, no jerk on the lead, just change direction. Your dog has to pay attention to where you're going instead of stubbornly charging ahead.
The role of equipment
A harness spreads the pull across the chest instead of the neck, which is gentler on the joints, but doesn't automatically make pulling any less. An adjustable lead that lets you quickly change the length during training is more practical help than any special anti-pull accessory. In our range, for example, the Trixie Premium dog lead, triple adjustable, or the Trixie Gipfel retriever lead with an infinitely adjustable neck loop.
To be honest
Loose lead walking takes repetition, not the perfect product. Expect it to take several weeks, with setbacks when there are lots of distractions outside. Being consistent on every walk achieves more than a single training session.
You'll find suitable leads and harnesses for everyday life in our dog lead guide or directly in the Harnesses & Leads collection.
